Outputs share a common GND between them and with the host PCB USB connector. === Protection Circuitry === All three supplies feature overcurrent protection through software-settable current limits that can be applied individually to each channel. Same-polarity aggressor protection and reverse voltage protection work up to ±15 V. === Tracking Mode === When the software-implemented tracking mode is active, Outputs 2 and 3 will track each other in absolute value by applying any voltage change made to one channel's setting to the other channel. E.g. if Output 1 is set to 12 V, then Output 2 will be automatically set to -12 V. ~~REFNOTES~~ ---- ===== Connectivity ===== The DPS3340 requires a host computer running the WaveForms software connected via USB to operate. ^ Device to Computer Interface | USB 2.0 Hi-Speed, Type B. | ---- ===== Power Requirements ===== The DPS3340 requires an auxiliary power supply. A compatible power supply is included with the purchase of the DPS3340. ^ Power Supply Voltage | 19 V +/- 5% | ^ Power Supply Current | 3.2 A maximum | ^ Power Consumption | 60 W maximum | ^ Barrel Connector Size | 5.5 mm x 1.65 mm | ---- ===== Physical Characteristics ===== |<100% 25%>| ^ Dimensions | 23.40 cm x 19.40 cm x 3.81 cm (9.2 in x 7.6 in x 1.5 in) | ^ Weight | 0.704 kg (1.55 lbs) | ---- ===== Environmental ===== |<100% 25%>| ^ Operating Temperature | 0 °C to 40 °C (32 °F to 104 °F) | ^ Storage Temperature | -20 °C to 60 °C (-4 °F to 140 °F) | ^ Operating Humidity | 10% to 80% RH non-condensing | ^ Storage Humidity | 5% to 95% RH non-condensing | ^ Cooling | Convection-cooled.
